ATTACHABLE VEHICLE BRAKE.

Application filed April 5,

My invention relates to vehicles brakes and more articular-1y to attachable brakes for autoino iles.

The object of my invention is to provide a strong, reliable brake of few parts and simple construction that can be readily attached to a wheel and adjoining parts of an automobile.

A further object of my invention is to ensure the relative rigidity of the various brake parts.

This invention shows a brake combination which is an improvement over my earlier invention as set forth in Patent No.

.- 1,452,439 issued April 17, 1923.

In said patent the brake actuating lever is secured to a bracket which in turn is secured to the radius rod of the vehicle; great difiiculty has been experienced in holding this bracket rigidly in place and it has been found to readily work loose after being in operation for a short while, thereby causing the brake to operate inetliciently. Inmy improved construction as set forth in this application, I overcome this difliculty by securing the actuating lever of the brake to the axle housing of the vehicle and the radius rod.

My invention is illustrated inthe accompanying drawings in which Fig. 1 is a perspective of the rear axle, adjoining wheels and drive tube of an automobile showing my improved brake attached thereto,

Fig. 2 is a side elevation showing the axle housing of an automobile and the positioning of the brake drum and adjoining parts relative thereto,

Fig. 3 is a vertical axial section thru the axle housing showing the preferred method of securing the intermediate brake operating lever thereto, and

Fig. l is a detail showing the connecting bar N.

Referring now to the drawings:

An attachable brake drum A preferably made in one piece and of pressed steel is adapted to fit snugly over the xle housing 13 and is held in place thereon by means of the U bolts a and screws a which secure said brake drum to the spokes c of the rear wheel C.

A brake band E provided with brackets e, e disposed one at each end thereof is held in position around the brake drum, by means of the supporting bracket d, which is sup- 1924. Serial No. 704,381.

ported by yoke member D firmly secured to the axle housing of the automobile by the threaded bolt d and nut 0Z One end of a bell crank lever F is secured at f to the lower bracket 6 and is connected intermediate its length at f to the lower end of the tension rod G, the upper end of the tension rod G being secured to the upper bracketc by the winged nut e A bracket H is secured to the radius rod K of the automobile and is provided with a slotted lug h on the outer side thereof, through which the tension rod G passes.

A spring 9 carried by the tension rod G is positioned between the lug h and the upper bracket 6, so as to tend to hold the ends of the brake bands apart.

Nut 9' threaded to the tension rod G is adapted to loosen or tighten the spring 9.

Referring now more particularly to Fig. 8, a lever supporting member L provided with an annular flange Z is internally threaded to receive the bolt d which passes through the axle housing B so as to firmly hold the lower prong 7c of the radius rod K and one end of yoke D to the axle housing.

Said member L is provided with a bearing portion Z and the hexagonal shaped extension Z An intermediate brake operating lever M is journalled on the bearing portion Z of the supporting member L and is held in place thereon by the spacing bar N provided with a hexagonal opening a at one end thereof which fits over the hexagonal extension Z of the supporting member L.

The spacing bar N is secured to the bracket H at n and is bored at a so as to receive one end of the spring 0 the other end of said spring 0 being secured to a bracket 39 on the connecting pull rod P (see Fig. 1) so as to assist in the return of the brake to open position after each braking operation.

It will be seen that the bar N acts as a locating member for bracket H and as a spacer between the bearing Z and the bracket H and locks L against rotation; L acting as a lock nut for lower radius rod bolt d.

The upper end of the bell crank lever F is connected to the intermediate brake operating lever M by the link 7.

A pull rod R, secured to the pedal S passes through the bracket I secured to the drive tube U and is secured at to the equalizing cross bar W. Rod P secured at p to the equalizing cross-bar V is connected to the bracket m formed integral with the intermediate brake operating lever M and transmits power from pedal S to the intermediate operating lever M.

lVhile I have described any Jaimproved brake connection as secured to one of the rear Wheels it will be seen from the drawings that I propose to have one such brake on the inner-side of each of the-rear wheels. WVhat I claim and desire to secure by Letters Patent of the United States is:

1. In an attachablebrake for an automobile; the combination of a brake drum, means for securing said drumto a wheel of said automobile,- operating means for exerting braking-pressure on said drum, a-principal bearing-to which said operatingmeans is secured, a supporttor-part of said operating means'secured to the axle housing, a bracket secured to the radius-rod acting as a support for another part of said operating means, and abar acting'as a locatingmemher for said bracket andas aspacer between said bracket and-'the principal bearing of said braking means.

' 2. In'an attachable brake for an automobile; the combination of a brake drum, means for securing said drum to a wheel of said automobile,operatingmeans for exerting-brakingpressureon said drum, a support for-part of said operating means securedto the axle housing, a bracket secured to the radius rodacting-as a support for another part 01 said operating means, a supporting niemben forming the principal bearing-of saidbraking means and a bar acting as a locating member for said bracket and as a vspacer between saidbracketand said supporting means which for-nssaid principal bearing.

3. In an attachable brake for an automo 5 bile;- the combination of a brake drum,

111g as a locating member for said bracket and as a spacer'between said bracket and said supporting neans which forms said principal bearing.

In an attachable brake for an automobile;e the combination of a brake drum, means for securing said drum to a wheel of said automobile, operating means-for exerting braking pressure on said drum, a support for part of said operatingmeans secured to the axle housing, a bracket secured to the radius rod acting as a supportitor another part of said operating-means, a sup porting member forming the principalbearing of said braking means, a-bar -acting as a locating member for' saidbra'cketand as a spacer between said'bracket and said-supporting means which forms said principal bearing and coactingmeans on said bearing member and bar-tor preventing the rotation of said bearing member.

In an attachable brake for an automobile; a brake' drum, means for securing said drum to a wheel of said automobile, a-brake band havingseparated ends, a brake band support mounted'on the axle-housing 'formaintainingsaid'brake band in -operating position with relation to said drum, operatin means inclnding twolevers adapted to draw said brake band ends-nearertogether for exerting-braking pressure onsaid drum, a support tor'oneof said levers of said operating means securedto-the axle housing, a bracket secured to the-radius"rod-acting as a support for said other lever ofsa'id operating means, a supporting member forming the principal bearing of-said braking means, a bolt-adapted to secure togethersaid bearing member, radius rod and axle housing, a bar acting as a-locating memberfor said bracket and as a spacer-between said bracket and saidsupporting -means which forms said principal bearing and 'coacting means on said bearing member and said bar for preventing the rotation of said bearing member.

In testimonywhere'of I have hereunto set my hand.
